2 high in humboldt?

[Rohnervillian]

Hello from Humboldt Co! I sure am glad and thankful for this awesome forum.My name is Sean, i live in northern Cali. and am also a full blown motorized bicycle junkie! I also have serious mechanical issues,I put a upgrade piston from crmachine, stage 2 head,and NT speed carb.Both test rides resulted in seize.BUT,not in the top end?both rides no farther than quarter mile. Any thoughts and suggestions much appreciated.

My suggestion?
Try putting a few miles on a stock engine before trying aftermarket go-fast options. I think you'll have better luck and enjoy your bike a lot longer than a 1/4 mile.

From what you've told us I can only assume you have Chinese 2 stroke engines.
If the engines seized I'll have to question your fuel mix. What ratio of oil to fuel are you trying to run? What oil?
